[1.7.10]Posting messages to chat client-side

[Chlod 0]

I'm trying to post a message to players, when they login, saying they need to update to the latest version. Now, I've done the whole "getting-the-version" thing. I just need to know what code to put to send the message ONLY WHEN the player logs into the game.

 

Thanks in advance

PlayerLoggedInEvent, though Ibelieve this event is fired only on the server side; if so and you absolutely must have an event that is fired on the client side (i.e. your mod is a client-side only mod), you can use EntityJoinWorldEvent and check for EntityPlayer before sending the message.

So now, what do I do to check if the Entity is a player, and how do I send the message?

 

EDIT: I can't find a tutorial for this exact version and topic on Google, so don't ask me to Google it. Done that already.

Done outside IDE, cannot guarantee if it will work from copy/paste, but the gist of it should be clear.

 

As this is for a client-side only mod, you could instead likely cast it directly to Minecraft#getMinecraft()#thePlayer() or whatever the structure of that is again.

public void getPlayer(EntityJoinWorldEvent event){
        //Check if the entity is what we are looking for.
        if(event.entity instanceof EntityPlayer){
                //If its a player, cast the entity to EntityPlayer.
                EntityPlayer player = (EntityPlayer) event.entity;
                //Now you use "player" instead of "event.entity"
        }
}

Ok, I did it. Now, how about the chat message now?

EntityPlayer#addChatComponentMessage to write message from client-side to client-chat.

I did it! Thanks guys!

Here's the results:

@EventHandler
public void getPlayer(EntityJoinWorldEvent event){
	//Credits: Matryoshika, Ernio and coolAlias on the Minecraft Forge Forums
        if(event.entity instanceof EntityPlayer){
                EntityPlayer player = Minecraft.getMinecraft().thePlayer; 
                    player.addChatMessage(new ChatComponentText("text));
        }
}

This will fire anytime ANY player joins world.

You need:

if (event.entity == Minecraft#thePlayer)

And ONLY that.

Ok... it doesn't fire at all. With the new changes and the past one.

It should be @SubscribeEvent, not @EventHandler. Might help you to check out a tutorial on using Forge Events.
